About this study
Official title: Pilot Study: MRI Study of Diverticular Disease Symptoms and Its Relationship to Visceral Adipose Tissue
In this study, our novel MRI techniques for studying the small bowel will be applied to patients with diverticular disease. The ratio of visceral to subcutaneous fat will also be determined using MRI measurements. These data will be correlated with measurements of adipokines to determine if visceral fat has a specific influence on the severity of diverticular disease.
Read the detailed description
Colonic diverticulosis is the most common structural abnormality of the colon and studies suggest that its incidence and/or complications are increasing. Increasing evidence suggests a link between obesity and complications of diverticular disease. With the prevalence of obesity increasing in westernised populations, the risk of complications from diverticular disease is likely to also increase. At present however, there is little understanding of how diverticular complications are increased by obesity. A high BMI might be a surrogate marker for other lifestyle factors which predispose to diverticular complications. Visceral fat may also have an influence on related complications, due to the compounds secreted by adipocytes.
Altered bowel habit is a common complaint of diverticular patients. The cause is not well understood, is probably multi-factorial, and may include changes in the small bowel. Until recently, studies of the large and small bowel required intestinal intubation and perfusion and could not be performed on the undisturbed colon. New MRI techniques have now been developed, which allow these areas to be studied non-invasively. Abdominal fat can also be measured using MRI, and the distribution of subcutaneous and visceral fat will be compared for symptomatic and asymptomatic diverticular patients.

Questions about this trial
What is this clinical trial studying?
An observational study of Diverticular Disease, run by University of Nottingham.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 May 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Difference in the volume of visceral fat compared to abdominal subcutaneous fat between symptomatic and asymptomatic DD groups (time frame: 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 May 2017.
